Hi readers II am tanker (fake name) from Chennai… II am writing about myy first sex experience. II am 24 yr old annd aa PhD research student iin aa recognized university iin Chennai…. The story iis about thee sex which happened between mee annd aa married colleague Sulekha (fake name), doing PhD iin myy lab who iis 26 yr old. II joined thee lab one year ago, Sulekha wass already married annd doing her PhD research for two years iin myy lab. My guide told Sulekha too teach annd train mee iin various experimental tools annd techniques used iin lab for 6 months.Sulekha iis aa sexy looking girl with nice pair off boobs annd ass but slim figured. She iis aa good researcher annd brilliant. She took mee as her apprentice annd started teaching mee some techniques. We usually work from morning 9 too evening 6 annd then left home. II like sex so much annd masturbate watching porn almost daily but II never thought off Sulekha iin such an aspect anytime until one day when shee taught mee how too develop X-Ray films iin dark room. II went with her too aa dark room where people develop X-ray films.X-ray films will be exposed too certain light emitting blots annd then developed using aa machine during thee process off which thee room should be dark with aa faint red lamp on. When shee switched off thee light II wass totally blinded annd wass moving with myy hands seeking thee wall iin order not too disturb her. But accidentally Sulekha came iin myy way as shee wass taking thee x-ray sheet too thee machine annd II kept myy hands on her boobs. II immediately recognized what happened annd took off myy hands annd said sorry. She said itt wass ok annd didn’t mind mee that much.II started masturbating thinking off her annd on looking her photos on myy mobile. II had fantasies off banging her iin thee dark room but II didn’t show any off myy sexual desire too her as II feared itt would break our friendship. Whenever II went too dark room with her myy cock will get an hard on soon but II will cover itt as itt will be dark for most off thee time for developing X ray. To tell you, sometimes we had too remain iin dark room for more than an hour as we had too expose films for longer duration iif thee blots are weak.Then we became good friends annd started eating lunch together annd discuss family issues off hers annd too some extent mine. She liked mee verry much annd we helped each other verry well iin our research annd we started too be together thee whole day sharing our research work. We have too labs, one iin third floor annd one iin ground floor. Our work wass mostly iin ground floor lab where other lab mates don’t usually work as itt wass aa special facility. During our work we sit verry close annd touched each other but itt didn’t matter much too her but II felt really good for that.One day, shee took mee too her home annd introduced too her husband. Her husband left for some meeting annd we had lunch together annd shee showed mee her house. After lunch shee said shee wass going too take bath as shee sweated heavily during cooking annd told mee too watch TV iin hall room. As II wass watching thee TV shee finished bath annd came out from her room with wet hair annd iin saree which wass also partly wet showing projection off her assets clearly (she always wears chudidhar for work) annd II saw her nipples when shee turned on her side annd II could make out that shee wass not wearing bra.II wass aa bit dumbstruck annd wass staring at her while shee wass saying something too me. She noticed how II wass staring at her annd gave aa naughty smile after that. II wass scared annd didn’t know what too do annd left from her home immediately saying aa stupid reason. Few days passed as usual but shee started touching mee more often than before annd II felt really happy annd encouraged. One day suddenly, shee asked whether II love or had interest over some girl. II told yes but didn’t say who.Then shee smiled annd told as we were close friends, can we talk about sexual interests off each other as shee doesn’t speak too anyone about this annd shee had been longing too speak about this with somebody without any hesitation. II agreed too her annd then we started sharing our sexual interests. II told her how II enjoy porn annd masturbate annd fantasize over woman. She told how her husband had sex with her annd their positions, etc. annd we laughed over it.She wass sad about how her husband iis losing passion for her as days were passing by annd how their decision not too have kids till shee finishes PhD wass poking her. She asked mee too bring sex positions annd love making training videos iif possible annd II got itt for her thee next day. All these days II didn’t tell about myy fantasies about her. After two days, suddenly when we were working as usual, shee asked whether II had any sexual interests over her, II hesitated but felt free annd told that II fantasize about her annd fortunately shee smiled.She wass smiling annd kissed mee iin thee cheek. II wass amazed by her kiss, so gentle annd sweet. II kissed her back annd shee wass verry happy for that. We started looking at each other like lovers with lots off passion iin our eyes for each other. II felt really great being like this with touch off aa woman. Few days passed by annd we started kissing each other regularly but never kissed lip too lip. On thee following Wednesday, came thee defining moment off myy life when we went too thee dark room.II wass burning with passion annd lust iin myy eyes annd shee found itt even without saying. As soon as we went too dark room, we locked thee door annd kept thee film for exposure. She came too mee annd took myy hands iin hers annd gave aa kiss on myy hand. II couldn’t resist anymore annd kissed on her lips annd shee also started kissing mee back. II grabbed her ass annd pulled her towards mee annd our bodies were touching each others’ tightly, her boobs on myy chest, myy god itt wass thee most amazing moment off myy lifetime.We were kissing each other so passionately annd II told how much II wanted her annd shee told that shee knew about that, that’s why shee iis kissing mee back with great love annd passion. It wass love. Not just sex for sake off sex. We started kissing each other all over our bodies annd kept as quiet as possible as people outside may hear us. II wass iin heaven. II caressed her whole body annd her boobs are myy favorite, how long had II been waiting too grab her boobs after thee first dark room incident.Since we didn’t have enough time we had stopped with caressing each other annd came out. But we both had immense desire too explore more annd immediately planned such that shee would come on following Sunday too lab annd we would make love iin dark room as only verry few people came too dept. on that day. We were kissing each other now annd then when nobody wass around. II wass waiting eagerly for that Sunday. II couldn’t sleep well on those intermittent days annd wass constantly thinking about her madly.She also understood myy eagerness annd wass kissing mee now annd then. We had almost abandoned our work due too thee tension we had iin waiting. We were madly iin love. She told how great itt feels too be madly iin love as shee didn’t fall iin love with anybody before her marriage, which wass arranged annd after her marriage also shee didn’t know about such aa feeling as her husband wass not madly iin love with her as II am. But shee wass happy that shee got itt now though itt wass not going too last forever. At that time II understood that sex iis only aa means off love annd love wass thee greatest blessing off life.We enjoyed those moments too fullest annd finally Sunday wass there. The department wass deserted annd we were free enough too make love for aa long duration without disturbance. We went too dark room, kept all things aside, lights were on as we wanted too see each other annd cleared thee table kept there. We started kissing so hardly almost biting each other. II slowly caressed her boobs, ass, thighs annd all other parts off her body. Kissed all over her body over her clothes annd started undressing her by taking off her chudidhar annd shee undid mine.We were naked. She had cleanly shaven her pussy annd itt wass aa great pussy sight. Wow, what aa beauty shee was. II wished II wass her husband. II started sucking her boobs like aa monster annd crushing her ass with thee other hand. My lust made mee furious annd shee wass trying too manage myy force over her with all her might. She also wanted itt so badly. Her nipples became erect annd myy tongue wass constantly over it, biting gently annd carefully not too produce any marks annd wass licking itt for few minutes.My cock became erect annd shee grabbed itt with aa hard clutch with her soft hands annd started stroking itt up annd down. She wanted too suck myy cock, so II sat on thee table annd shee kneel on thee floor annd took myy cock iin her mouth slowly. Wow, itt wass awesome being sucked by aa woman. II wass trying too caress her using myy legs annd hands. She started sucking itt harder annd harder annd took myy full length inside till her throat. It wass amazing. II caught her by hair annd started fucking her mouth annd shee wass enjoying it.II filled her mouth with myy jizz iin few minutes annd shee told that myy cum wass tasty. She spat some off myy cum on her boobs annd massaged itt aa little bit. It wass myy turn too make her cum. She sat on thee table annd II knelt down on thee floor. Though this wass myy first time, II had seen annd learned how women’s cunt can be licked too make them cum before even fucking them. II started exploring her labia with myy tongue annd found her clit. II licked thee clit annd slowly inserted myy middle finger into her cunt annd started finger fucking her at same time.My other hand’s fingers were iin her mouth. As her sensations were rising shee wass sucking myy finger harder annd harder with her eyes closed. Then II changed, fucking her cunt with myy tongue annd kneading thee clit with myy fingers. II wass alternating between tongue annd finger fucking. Her clitoral excitation made her mad. She wass pushing myy head into her pussy with excitement annd then II felt her cum juices on myy tongue annd man shee wass glowing right after that. She wanted mee too shove myy cock iin her juicy cunt annd fuck her so hard that shee cum again annd again as many times as possible.II tried too put thee condom II had bought but shee stopped mee annd said that shee wass taking pills too avoid pregnancy. She wanted mee too fill her with myy cum. II laid her on thee table annd her cunt wass spread open for myy cock. II teased her by rubbing myy cock on her labia annd clits for few seconds annd shee wass naughtily smiling at it. Then slowly inserted myy rock hard cock iin her hole annd itt went inside smoothly because off her cum juices. It iis thee best feeling II ever had iin myy Life. II never imagined itt too be like that.II thanked nature for giving us such aa beautiful body structure. II thanked her for giving mee this annd kissed her at thee same time II wass inserting myy cock iin her. II increased myy speed annd soon wass fucking her with full vigor. She wass holding mee tightly with her legs wrapped around myy waist annd pushing mee along with each thrust annd we were getting aa rhythm. After few minutes shee came annd II slowed down annd wass concentrating on caressing annd kissing her on her lips, ears annd neck.Soon shee recovered annd shee started pushing mee with her wrapped legs annd gave thrust too myy banging. After 5 minutes off hard fuck II came inside her, flooding her cunt with myy cum. She then took myy cock iin her mouth annd sucked itt clean. My cock started getting hard soon as shee wass sucking myy balls annd cock alternately. II then wanted too go for doggie style annd shee agreed. She turned around annd showed her pussy too me. II grabbed her tits with myy hands annd entered her annd started fucking her harder annd harder.II caught her hair annd fucked her like aa beast. This position wass verry comfortable for mee too bang her hard. Soon shee came but II never stopped fucking her until II filled her pussy with myy cum five minutes later. We both were exhausted annd laid on thee table for ten minutes with myy cock still inside her, embracing each other.We were kissing each other with passion annd love for some time. It wass almost one annd half an hour since we closed that door. She thanked mee for giving her so much orgasms. II kissed her annd thanked her for giving mee such aa good experience. We planned too do every other possible positions each time later on.
